FAQs

Q: How do Crest 3D White Whitestrips work?

A: Crest 3D White Whitestrips are thin, flexible strips that are coated with a tooth whitening gel. Designed to conform to the shape of your teeth, they work by keeping the teeth whitening gel in place against your teeth to remove stains below the enamel surface. Whitestrips use the same, effective whitening ingredient dentists use. They deliver the whitening you need where you need it for a brighter, whiter smile!

 Q: Why should I use Crest 3D White Whitestrips? Why isn’t a whitening toothpaste enough?

A: Because you shouldn’t settle for a smile that’s just “white enough.” Every Crest 3D White Whitestrips teeth whitening system guarantees a whiter smile. While Whitestrips and most whitening toothpastes remove surface-level stains, Crest Whitestrips remove set-in stains below the enamel surface for a visibly whiter smile.

Q: Can Crest 3D White Whitestrips damage my teeth or enamel?

A: Crest Whitestrips are proven to be safe to your teeth as demonstrated through extensive clinical trials. Whitestrips use the same enamel-safe ingredient, hydrogen peroxide, which many dentists use in their offices. In fact, Crest Whitestrips also strengthen your enamel with a soothing serum.

When used as directed, it’s a safe and effective addition to your beauty routine.
